Biososteric Replacement in the Design and Synthesis of Ligands for Nicotinic Acetylcholine Receptors
摘要:
A series of ethers containing pyrrolidine and/or pyridine bioisosteres was synthesized and evaluated as nicotinic ligands. The dimethylarninoethoxypyridines 6 and 7 inhibited the specific binding of (-)-[H-3]Nicotine with Ki values of 300 nM and 450 nM, respectively. Compounds 8 and 9 were found to have Ki values of 3390 nM and 360 rim. These results suggest that dialkylarnino and appropriately substituted benzene rings (NO2, 8; OH, 9) are bioisosteric replacements for pyrrolidine and pyridine, respectively.
